Abstract:
To achieve a large thickness of conductive metal-containing material in a feature of a product unit processed with a liquid-based etch process, the desired thickness of material is apportioned to the two opposing surfaces of a substrate to create a two-part feature. Conventional features are made by identically patterning two same-thickness metal-containing layers and electrically connecting the resulting patterned parts in any suitable manner. However, features may also be made that do not have identical parts on opposite sides of the substrate, the two parts being electrically connected but differing in thickness, in shape, or both. Moreover, having two metal-containing layers separated by an insulator is also useful for allowing different sections of the same feature or circuit to cross one another without shorting, or to overlap in whole or in part without shorting.
Abstract:
The rough conducting structures (GL) and the fine conducting structures (FL) are etched out of a metal layer in a common etching process, whereby an etch resist structured by means of photolithography is used in the area containing the rough conducting structures (GL) and an etch resist structured by means of a laser beam is used in the area containing the fine conducting structures.
Abstract:
A laminate (50) comprising metal layers (56 and 58) separated by an etchant barrier (51) to control depth of etching of the laminate, the barrier being etchable by an etchant which is not an etchant for the layers. A cable (20) incorporating such a laminate and having relatively flexible conductors (22) integral with relatively rigid terminals. A method of making such a cable, using the laminate, by selectively etching the layers down to the barrier to form the conductors and terminals (26 and 28), stripping the barrier and laminating the conductors with an insulating material (42 and 44) preferably extending over at least a portion of the terminals to reinforce the conductor terminal transition and a cable when made of such a method.
Abstract:
Examples are provided for a flexible circuit element including a flexible insulating support structure, a solid metal trace extending at least partially between a first connector and a second connector on the flexible insulating support structure, and a liquid metal conductor disposed in contact with the solid metal trace in a region of the trace configured to repeatedly flex when installed in a device.
Abstract:
The invention provides a process of forming a continuous pattern on a surface composed of two or more surface regions, each of the regions being of a different surface energy, the process utilizing a novel ink formulation for printing on such multi-region surfaces.
Abstract:
Described are an apparatus and a method for printing a high aspect ratio and/or specific vertical geometry pattern. The apparatus operates in a multi-pass printing mode and includes one or more paste dispensing mechanism configured to dispense a high viscosity paste to form a pattern on a substrate. At least one paste dispensing mechanism is configured to dispense the paste to a segment of the pattern printed at an earlier pass. The paste is dispensed to the relevant segment of the pattern earlier printed before the paste printed at the earlier made pass is dry or what is termed "wet- on-wet" printing.
Abstract:
A method for manufacturing a non-planar printed circuit board assembly (1) is disclosed. The method comprises providing a planar formable substrate (2) for supporting a conductive material (3) and at least one electronic component (4), printing a circuit pattern of an uncured conductive material (3) on the planar substrate (2), forming the substrate (2) and the uncured conductive material (3) into a non-planar shape, and curing the conductive material (3),wherein the substrate (2) comprises a metal sheet and an electrically insulating coating (2b) arranged between the metal sheet and the conductive material (3).
